Brooklynne had been missing since at least 2:18 p.m. Wednesday, when officers conducting a welfare check at her Knoxville home discovered the body of Kimberly Enix, 36. Her coworkers called police after the woman failed to show up at work, officials said.

A billboard alert informing passersby that Brooklynne was missing was also launching nationwide.

"Help us #FindBrooklynne," the Knoxville Police Department tweeted.

“Bring Brooklynne somewhere safe,” Knoxville Police Chief David Rausch said during a press conference Thursday, speaking to the child’s father. “Drop her off with someone safe. This is about (Brooklynne). We know you love the child. You care about the child.”

Law enforcements pleas were answered when a citizen who heard the Amber alert on the radio realized he was behind Kimberly Enix's black Chevy, police said.

"The citizen called 911 and deputies with the Morrow County Sheriff’s Office responded and initiated a traffic stop. Enix was taken into custody without incident. His 2-year-old daughter Brooklynne was recovered and is safe," TBI said in a statement.
